INTERLOCKING DOUBLE TWIN-SzTUD WALL STRUCTURE.

Applicationfiled September 21, 1926, Serial No. 136,796. Renewed May 2, 1923.

This invention relates to wall structures and is an improvement on structures of the kind set forth in my Patent No. 1,593,180, dated July 20, 1926. in which a form of innor and outer sets of studs are employed for inner and outer wall bodies.

An object of my present invention is to provide a rigidly reinforced wall of extreme simplicity and of common stocksteel elemerits, and to eliminate specially formed or shaped steel.

Another object is to provide cross connected pairs of'twin studs in which the outer pairs of twin studs are arranged in an outer plane set and the inner pairs of twin studs are in an inner plane set, and an object is to provide horizontal bracing fixed to the studs and also to provide diagonal bracing to obtain earthquake, tornado and cyclone resistance in a wall structure.

A further objectis to provide a double wall structure in which a fabrication interlocks the foundation, the wall and roof elements, and an object is to provide inner and outer wall bodies each having its own set of twin studs, and to provide for cross connection of the wall bodies in either very close or suitable spaced position.

An additional object is to provide a wall and method of making same in monolithic form by casting cement and gypsum or other plastic materials or built with units or blocks of various materials, wherein lava or.

stone block (natural or artificial) may be employed and which may be capable of being welded or fused into a bond joint.

Other objects and advantages will be made manifest in the ensuing specification of the embodiment of the invention here illustrated; it being understood that modifications, variations and adaptations may be resorted to within the spirit, scope and principle of the invention as it is here claimed.

Figure 1 is a perspective of the 'wall; parts being in section.

Figure 2 is a plan; parts being in section.

Figure 3 is a horizontal section of a double twin stud group.

Figure a is a vertical cross-section and elevation of wall parts.

v Figure 5 is an elevation of a broken away outer wall and its foundation.

Figure 6 is a perspective of a form of in a foundation or sill 2 parallel, horizontal bars 3 to which are secured the lower ends of respective pairs of outer, studs S and in side twin studs S spaced as required in different wall structures. The outside pairs of studs plane set opposed to a plane set formed by the inner pairs of studs S, and these plane sets are for holding respective outside and inside wall bodies O and I, which may be spaced, as here shown, or may be built in close relation just clearing intermediate diagonal bracing (later described).

The studs maybe braced atl6 to the anchor pieces 3 and the pairs of studs are pitched at required spacing along the foundation in their respective inner and outer set or plane arrangement.

Opposed twin pairs S and S are solidly cross connected by bolts orpins 7 atsuitable vertical spacing and the distance between the connected twin pairs is determined by pipe spacers 8, which may be short or long. It is necessary to space the studs. constituting a pair, so as to receive therebetween, horizontal reinforcing rods or bars 10 at different heights. Therefore, be tween studs of each pair there is placed on the bolt or tie 7 a short spacing block or disc 9, Fig. 3. The bars 10 are initially shiftable, when in place, so that wall blocks AB can be set into position and then the bars 10 can be dropped into the top channels a in the blocks, Fig. 4:.

Preferably, sill bars 11 are laid in the foundation 2 to interlock in bottom channels in the respective blocks A-B and so rigidly lock certain intermediate blocks which do not lock on studs. The vertical ends of some of the blocks are grooved to receive portions of the vertical studs and the blocks to butt end to end.

After the horizontal bars have been finally laid in interlock with a lower block course they are then, when desired, fastened to the studs S-S at corners and ends of bars by bolts, or rivets 12.

At wall intersections the studs are of angle-iron form S During fabrication diagonal braces 13 are installed and suitably fixed on the cross spacers 8 of the connected pairs of twin studs.

The upper ends of the outer and the inner sets of stud pairs are capped by T-iron bars 14: which form a solid support for a plate .5 are arranged to form an outer.

7 parts are bolted or riveted, the method of 15 carrying joists 16 and rafters 17, both of which are bolted' through the plate to the cap bars 14. Thus the roof parts, the studs and foundation are all interlocked.

The wall blocks A may be of various kinds of material, including cut or cast lava It is understood that where any of the Weldingthe same may be employedif desired.

WVhat is claimed is p 1. A reinforced building wall including a foundation with embedded, parallel, upwardly projecting anchorage bars, an inner system of pairs of stud bars, the studs of the pairs embracing one line of the said bars, an outer system of pairs of stud bars which embrace the outerv line of anchorage bars, an outer wall body built up from the foun dation and embedding the outer system of stud bars, an inner wall body built up'from the foundation and embedding the inner stud bar system, opposed pairs of said studs being cross-connected by vertically spaced cross bolts carrying means to space the studs of a pair and space the opposed, connected pairs, and horizontal reinforcing bars passing between the stud bars of the pairs and being secured thereto;

2, A reinforced building wall including a foundation with parallel, longitudinally extending anchorage bars set edgewise in and projecting up from the topthereof, inner pairs of stud bars which embrace" the inner line of anchor'bars and outer pairs of stud bars which embrace the outer line of anchor bars, cross bolts connecting opposed pairs of the stud barsa-nd having spacers to separate the pairs and the studs of the pairs, inner and outer wall bodies respectively the inner and the outer systems of studs, and

diagonal bars connected to respective cross bolts and lying between the-wall bodies.

A building Wall including a system of opposed pairs of stud bars which latter are spaced laterally apart in 'theirpairs, horizontal' reinforcing means for therespective systems, spacing means for the respective systems, wall bodies built on said systems, T-bars longitudinally capping the respective systems of stud pairs, and a plate supported on the topof the T-bars.
